Description
Antonin Trimaille writes a 2026 commentary on predicting how fully a replacement heart valve will expand after implantation. Catheter-placed aortic valves are being offered to younger, lower-risk patients who will live with them for decades, so durability now matters more than ever. How evenly the valve frame opens is a key part of that durability.
Scans a month after implantation show more than half of these valves significantly underexpanded in a landmark study. Uneven opening deforms the frame, narrows the pockets behind the leaflets, and is tied to clotting on the leaflets. Underexpansion of one valve model was also linked to more deaths, strokes, and hospital returns at one year. Trimaille argues that better prediction of expansion, before and during the procedure, is a concrete step toward valves that last.
